March 25Mar 25 Hi! Yesterday I upgraded my NanoPi Neo Plus2, during that the kernel version went from 6.12.74 (package version 26.2.0-trunk.478) to 6.18.19 (package version 26.2.0-trunk.626). This morning I noticed, that this kernel is missing the dm-snapshot.ko module. I searched the forum if anyone else is having this problem, but it appears I am the only one using this feature. I use snapshots to create consistent backups of the system. Is there a reason why it was removed and more importantly is there a way to get it back without having to compile the kernel myself? Greetings PS: I should note, that I want the module back in newer kernel versions in the future. For now I downgraded to some older version that I was able to find a package for and got it working through that. Edited March 25Mar 25 by Frank F. Added note about workaround via downgrade
March 25Mar 25 Feel free to use ./compile.sh BOARD=nanopineoplus2notsurehowitsnameis BRANCH=current kernel-config and then build a kernel packages with the adjustments. Once installed and tested, you can PR to these kernel config here: https://github.com/armbian/build/tree/main/config/kernel
March 25Mar 25 Author I'm still working on getting the kernel compiled, but in the meantime I may have found where the option disappeared, back when 6.18 was still edge. https://github.com/armbian/build/commit/2a38243de9ff01e079b6ec0c930c00f892e163aa#diff-003c7426ff865cb4e5d2d17e324129fe9de266da1f83a11e290670929e55036dR10-L675
March 25Mar 25 Author Solution I opened PR #9590 with the really minimal change that's needed to get my desired behavior back.
